Done. Seems there was a change in the name of the article hence the link was broken. Updated it.

After Blueprint patches got merged, it should be still possible to change values from an external file - Please find more information here [0] on how to use it. Full details on Blue Print are here [1]

2016-05-22 22:06:21 -0700 answered a question you are not allowed to upload merges

I encountered with same (similar ) problem Gerrit: remote rejected (you are not allowed to upload merges)

Rather than doing a rebase of the patch, I did a cherry-pick of the patch on to a branch (which is based on updated master or stable/beryllium in my case) , resolved conflicts if any that arises due to cherry-pick and uploaded the patch. It worked like a charm . Following are steps.

git checkout stable/beryllium; git pull

git checkout -b new_branch

git fetch refs/changes/89/38489/3 && git cherry-pick FETCH_HEAD

git mergetool -t meld

git cherry-pick --continue

I am aware of the command on how to bring down a link ( link s1 h1 down) in mininet. Looking for a command which will bring down only host in mininet (not killing all hosts), but a specific host.

2016-05-02 13:48:52 -0700 answered a question unable to modify code L2 switch

I hope you are modifying the lines in master.

L2switch Master fails on check style violation --> which means the indendation , unused imports, extra spacing matters during compilation phase.

Please check the 6 checkstyle violations and rectify it. Happy to help you if you would like to paste the errors here.

Hope it helps.

The error is due to

The plugin - maven-checkstyle-plugin:2.16 is erroneous

Also there are recent changes in maven settings file.

Hack :-

Go to settings.xml in .m2 folder & Change https to http and it should work fine.

odl-restconf feature might be installed when you try installing other features like "ui". So when you install again the same feature it throws you error. Hope this is helpful.

Thanks Karthik, but my question was to delete a specific flow on a device.

I would like to know how to delete one of the below mentioned specific flow (NOT all flows) installed on mininet ?

I am aware of how to delete a flow through restconf. I am looking for command to delete a flow something like "ovs-ofctl del-flow ...."

2016-04-05 17:30:57 -0700 answered a question default flow entries in Helium vs Lithium

It seems Heilum is only pushing only on eaction, but where as Lithium code base pushes two actions. The second action in helium involves in sending packet to controller also.

Two actions example :-

<action> <order>0</order> <output-action> <output-node-connector>openflow:1:2</output-node-connector> </output-action> </action> <action> <order>1</order> <output-action> <output-node-connector>CONTROLLER</output-node-connector> <max-length>65535</max-length> </output-action> </action>

Stop the controller

Go to distribution/karaf/target/assembly/etc

Remove line 128 from and corresponding "," and "\" from the line 127

Start the controller and you should be good.

2016-03-21 11:25:55 -0700 answered a question is it possible to rename a node?

i don't think it is possible to rename a node (it is unique identity through which controller is able to identify/establish a connection to switch)

You can disconnect the switch and then change id and then connect to the controller with a different id

Hi Walid i updated My above accepted answer. Please let me know if you couldn't connect still

2016-03-18 12:34:12 -0700 edited answer L2 switch build errors

I think you built the project based on master. Please try to checkout stable/beryllium and give it a try. The following steps should give a success.

git clone

git checkout stable/beryllium

mvn clean install -DskipTests

These are the steps that i follow in order:-

git clone

cd l2switch

git checkout stable/beryllium

mvn clean install -DskipTests

cd distribution/karaf/target/assembly/bin

./karaf debug

feature:install odl-l2switch-all

then in a new terminal start mininet with following command (OF13, 1 switch - you can change parameters as needed)

sudo mn --controller=remote,ip= --switch=ovsk,protocols=OpenFlow13 --topo=linear,1 it shows connnected to controller

You can checkout who is listening on ports by using command "netstat -an"
